摘要： Counter circuit including four bistable stages arranged to count upward through a recurring sequence of combinations of operating states of the bistable stages in response to trigger pulses. An output circuit produces an output signal when the bistable stages have counted upward to the highest count before repeating the sequence. A setting circuit in each bistable stage can switch its stage into either the ''''1'''' or ''''0'''' state at any time during a sequence. Setting signals are applied at input terminals of each setting circuit and are gated in to set the bistable stages simultaneously by a strobe circuit.

摘要： A process for plating a flexible electrically conductive material such as metallic tape with a thin stripe of metal by passing the moving tape around a groove in the periphery of a disc which is rotated at the same speed in the direction of travel of the tape. Plating solution is supplied to the peripheral groove of the disc to contact the underside of the tape therein, the solution being confined in a narrow channel in the groove so as to plate only that area of the tape immediately above the channel.

摘要： An apparatus which receives a sequence of input pulses and generates a staircase waveform. The input pulses activate a sampler which samples the value of a periodic sawtooth voltage. The sampled values are maintained in the intervals between input pulses by holding capacitor. In a preferred embodiment the periodic sawtooth voltage is synchronized by the input pulses.

摘要： METHOD OF METALLIZING AN INTEGRATED CIRCUIT NETWORK CONTAINING AN ARRAY OF IDENTICAL CELLS TO PRODUCE A SPECIFIC SYBSYTEM. EACH IDENTICAL CELL INCLUDES SEVERAL GROUPS OF COMPONENTS, EACH GROUP BEING CAPABLE OF BEING INTERCONNECTED IN SEVERAL DIFFERENT ARRANGEMENTS TO FORM SEVERAL DIFFERENT BASIC LOGIC CIRCUITS. A FIRST IDENTICAL METALLIZATION PATTERN IS PLACED ON EACH CELL OF THE ARRAY AND INCLUDES ALL THE DIFFERENT ARRANGEMENTS OF INTERCONNECTIONS BETWEEN THE COMPONENTS OF EACH GROUP OF THE CELL, AND ALSO A BLOCK OF METAL ADJACENT THE CELL. TO COMMIT EACH CELL TO A SPECIFIC LOGIC ARRANGEMENT, METAL IS REMOVED SO THAT EACH GROUP BECOMES ONE SPECIFIC BASIC LOGIC CIRCUIT AND SO THAT THE BLOCK OF METAL BECOMES A FIRST SET OF DISCRETE CONDUCTIVE PATHS. A LAYER OF NON-CONDUCTIVE MATERIAL IS APPLIED OVER THE ARRAY, OPENINGS ARE MADE THEREIN TO EXPOSE APPROPRIATE AREAS OF THE FIRST METALLIAZATION, AND THEN A SECOND METALLIZATION PATTERN IS APPLIED TO FORM A SECOND SET OF CONDUCTIVE PATHS GENERALLY TRANSVERSE TO THE FIRST SET. THE SECOND SET IN CONJUNCTION WITH THE FIRST SET INTERCONNECTS THE BASIC LOGIC CIRCUITS INTO A SPECIFIC SYBSYSTEM.

摘要： An attenuation circuit including a field effect transistor and a bypass circuit coupled to the field effect transistor for providing a wide range of attenuation values. An input signal to be attenuated is applied to the drain electrode of the field effect transistor and also to the bypass circuit, and a DC control voltage is applied to the gate electrode of the field effect transistor and to the bypass circuit. The field effect transistor and the bypass circuit each operate to cause attenuation of the input signal by a predetermined amount. As a result, the input signal applied to the drain electrode of the field effect transistor and to the bypass circuit is attenuated by a total amount related to the combined values of attenuation provided by the field effect transistor and the bypass circuit and applied via the source electrode of the field effect transistor to an output terminal.

摘要： The arc tube of an arc discharge device is closely surrounded by, but spaced from, an optically transmissive envelope. The space between the tube and the envelope is filled with a transparent, inert, heat-transfer fluid. Forced cooling of the exterior envelope wall permits the arc tube to be operated at a substantially uniform wall temperature, at a high efficiency and high-wall loading.

摘要： A signal receiver includes gated automatic gain control (AGC) circuitry having an amplifier stage coupled by a first unidirectional conduction device to a gate pulse signal source and by a second unidirectional conduction device to RF and IF amplifier stages whereby the first unidirectional conduction device prevents ringing in the gate pulse signal source from affecting the AGC action and the second unidirectional conduction device tends to sustain a substantially constant level of AGC signal intermediate the period of gated pulse signal application.

摘要： A device for supplying a pulse when a pulse is missing from a continuous train of pulses. The continuous train of pulses passes directly through the device and also to delay lines which delay each pulse so that it appears at the input of a gate circuit at approximately the same time as the next successive pulse would appear at the output of the device. If a pulse is missing, a previously received delayed pulse is passed by the gate to the output. When a pulse does appear, it inhibits the gate circuit from passing the delayed pulse.
